FURNITURE-SUPPORT.

Patented Dec. 15, 1908.

1907. Serial No. 383,436.

To all whom it may concern:

Be it known that I, EUGEN I'IACKH, a

citizen of the German Empire, residing at Stuttgart, in the Kingdom ofWurtemberg, Empire of Germany, have invented certain new and usefulImprovements in Furniture- Supports, of which the following is adescription, reference being had to the accompanying drawing, and to theletters and figures of reference marked thereon.

This invention relates to an improved support for furniture of differentkinds such as chairs, couches, tables, pianofortes, and the like.

The invention consists essentially of an elastic or resilient deviceinterposed between the piece of furniture and the surface on which thelatter rests, so that said device may absorb not only all the vibrationscaused in the piece of furniture when in use, but also those vibrationsproceeding from the floor or surface itself on which the piece offurniture rests.

The object of the invention is clearly seen in the several examplesdepicted throughout the figures of the accompanying drawing, in whichFigure 1 is a vertical section of the lower part of a piece of furnituresuch as the foot of an article. Fig. 2 is a bottom plan view of thedevice represented in Fig. 1. Fig. 3 is a sectional top plan, and Fig. 4a bottom plan of a frame which may belong to another article offurniture.

Similar numerals of reference designate corresponding arts throughoutthe different figures of the rawing.

a designates the foot of a piece of furniture shown here simply by wayof example. In this foot is arranged a circular ring I; of suitableelastic or resilient material, such, for in- I stance, as india rubber.At the center of the foot a is an elastic ball 0. This ball 0 is heldwithin the cup-shaped end of a screw d which is vertically adjustable soas to regulate the position and pressure of the elastic ball 0.

In Fig. 1 it is seen that the ball 0 is the actual support for the foota, and that the ring I) does not come into requisition until after theball 0 has been more or less depressed. Assuming that this foot a isattached to a chair, the ball 0 will be compressed first and afterwardsthe ring I), which serves in effect as the elastic sole beneath the footand on which the chair is supported. If a person using a chair thusfitted moves, for instance, somewhat forward, the ring Z) will becorrespondingly compressed without the person being affected in any way.

In the form of construction shown in Figs. 3 and 4, the ball 0 isarranged the same as it is in Figs. 1 and 2, and the elastic ring b is ahalf oval shape and not completely circular, as in Figs. 1 and 2.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

The combination with a piece of furniture, of an elastic ball, acup-shaped regulating screw for controlling the same, and a curvedelastic tread surrounding the ball, all combined and operatingsubstantially as and for the purpose set forth.

In testimony whereof I afiix my signature, in presence of two witnesses.

EUGEN HACKH.
